Stamps are sold in far more places than most people realize, and knowing where to buy them saves a trip to a post office line. This guide covers what each type of postage pays for, which stores keep booklets behind the register, how to spot a counterfeit listing, and which picks are worth keeping on hand.

Stamps Explained: What They Are and Who They Help
A postage stamp is a small adhesive label issued by the United States Postal Service that prepays delivery of a letter, postcard, or lightweight package. Stick one in the upper right corner of the envelope and the carrier handles the rest. USPS sets the rates, approves the artwork, and releases new issues every year.
Who still buys stamps? Small business owners mailing invoices, grandparents with holiday cards, freelancers returning contracts, anyone filing a paper tax form, and collectors chasing a limited pane. Stamp collecting is still an organized hobby here, with the American Philatelic Society, the national membership body for it, running shows and authentication services. For household mail the format that matters is the Forever design, which holds its first-class value through every future rate change.
How to Choose Stamps: Features That Matter
Match the denomination to the piece you are mailing, then match the quantity to how often you mail. The rest is artwork.
Forever denomination. It never expires and never needs topping up, so a book bought now still carries a standard envelope after the next increase.
Domestic versus international. A regular Forever covers U.S. addresses only. Anything crossing a border needs a Global Forever, which pays the international letter rate to any country. Mixing the two up is the most common reason a piece bounces back.
Format and quantity. Booklets of 20 fit in a kitchen drawer. Coils of 100 suit a home office that mails invoices in batches. Panes and full sheets are what collectors and paper crafters buy.
Special-use rates. Anything heavier than an ounce needs added postage, and square, rigid, or lumpy envelopes need a nonmachinable surcharge. Buy the correct extra-weight issue rather than stacking two Forever designs.
Artwork and theme. Commemorative releases honor artists, athletes, wildlife, and anniversaries, and they are the ones worth buying for special occasions. Flag designs stay neutral, which is what business mail wants. Shopping for festive envelopes too? Our Christmas card buying guide pairs with the holiday releases.
| Type | What it pays for | Best for |
|---|---|---|
| Forever | First-Class letter up to one ounce, domestic | Everyday household mail |
| Global Forever | International mail, one rate to any country | Overseas cards and documents |
| Postcard rate | Domestic postcards | Save-the-dates, thank-you notes |
| Extra weight | Each unit past the base weight | Wedding invites, thick cards |
| Nonmachinable | Square, rigid, or lumpy envelopes | Square invitations |
Prices sit on the official site and change whenever a new rate is filed, so confirm the figure there rather than trusting a printed number.
Stamp Buying Mistakes to Skip
The costliest mistake is chasing a discount that should not exist. Legitimate postage sells at face value almost everywhere, so a steep markdown is a warning, not a bargain.
Buying deep-discount listings. The U.S. Postal Inspection Service reports that counterfeit postage is typically sold in bulk at 20 to 50 percent below face value, most often using the American flag artwork. Fraudulent postage does not get delivered, and the buyer absorbs the loss.
Assuming every marketplace seller is authorized. Third-party storefronts are not automatically Approved Postal Providers. Buy direct from USPS or from a retailer holding a resale agreement.
Treating old denominations as drop-in replacements. Pre-Forever issues printed with a dollar amount stay valid, but only at that printed value, so several have to be combined to reach today’s rate.
Skipping the weight check. Wedding invites and thick holiday cards tip past the base weight constantly. A cheap kitchen scale settles it in five seconds, or the recipient gets a postage-due slip instead of a card.
Which Stores Carry Stamps
Post offices, Walmart, Target, most large grocery chains, pharmacies, office supply stores, banks, The UPS Store, and many 7-Eleven locations sell stamps over the counter. Almost none put them on an open shelf. Ask at a register.
Post Office and Automated Postal Centers
The retail counter carries the full catalog: Forever, Global Forever, postcard rates, nonmachinable issues, current commemoratives, and collectible panes. Staff will weigh a tricky envelope before you pay. The self-service kiosks in the lobby of most larger branches run around the clock, and the location finder shows which ones stay open overnight.
Walmart and Target
Both keep booklets at the customer service desk and the main registers, stored out of sight rather than on display. Some Walmart Supercenters also stock coils of 100. If your store is out, the in-store bank branch often has some.
Grocery and Pharmacy Chains
Kroger, Safeway, Publix, and Wegmans hold stock at the customer service counter. CVS and Walgreens sell Forever booklets at the front register, usually one artwork option, but the hours are long and both shelve envelopes, greeting cards, and pens a few feet away.
Office Supply and Shipping Stores
Staples, Office Depot, and OfficeMax stock booklets near the shipping desk, which also accepts USPS, United Parcel Service, and FedEx drop-offs. The UPS Store sells them at the counter too. Restocking anyway? Our school supplies and stationery guides cover the rest of the trip.
Banks, Credit Unions, and Convenience Stores
Plenty of bank and credit union branches sell books to account holders at face value, and some Bank of America and Chase ATMs dispense them alongside cash. Among convenience chains, 7-Eleven is the most consistent, though any one location can be out. Call ahead, and call the post office too if you want a specific commemorative issue, since smaller branches sell through them fast.
Best Places to Order Stamps Online
The official USPS store has the deepest selection. Amazon and the big-box sites carry the common Forever booklets, and Stamps.com is where you buy postage if you mail at volume.
USPS.com
The widest catalog anywhere: Forever booklets, Global Forever, coils of 100, collectible panes, and first day of issue covers. Some limited releases sell only here before they run out. Shipping terms and the delivery window show at checkout. Browse the official store.
Amazon
Authorized resellers list Forever booklets and full sheets, and Prime handles the shipping. Ignore any listing priced meaningfully under face value, whatever the explanation. Safer approach: browse the office products bestsellers, where the top entries are established sellers.
Stamps.com
A subscription service for printing USPS postage on a home printer. NetStamps sheets cover ordinary letter postage; the same account prints shipping labels, adds tracking, and offers GlobalPost when you ship packages abroad. The monthly fee only pays for itself at volume.
Walmart.com and Target.com
Both list the current flag booklet at face value. Narrow selection, but an easy add-on to an existing order.
What Buyers Are Reporting About Online Deals
The loudest complaint in buyer discussions is not price, it is authenticity. USPIS says the volume of counterfeit postage moving through online platforms has escalated, spreading via social media marketplaces and third-party storefronts. On eBay’s community boards, longtime sellers repeatedly flag suspicious Forever listings and sum up the tell in one line: nobody sells current postage below face value. Snopes has fact-checked the same pitch as a recurring scam, and news outlets covered customs inspectors in Chicago seizing roughly $118,000 in fakes in one interception.
The quieter half of that consensus is more useful. Buyers who stay with authorized sellers report no trouble. USPIS notes that legitimate big-box and warehouse retailers pass along very small discounts under resale agreements, so a token markdown at a warehouse club is normal while a half-off deal is not. Inspectors add a physical check: current issues use ink that fluoresces under UV light, and counterfeits generally do not.
Our Top Stamp Picks
These five cover the situations most buyers land in: everyday mailing, high-volume office mail, overseas post, and collecting. Face value moves with each rate filing, so confirm the current figure before ordering in bulk.
Best overall: USPS Forever Stamps, Booklet of 20. The everyday workhorse, roughly a month of household mail for most families. Shop on Amazon, buy direct, or grab one at the Walmart service desk.
Best for high-volume senders: USPS Forever Coil of 100. A roll for home offices and small businesses batching invoices, priced at 100 times the current first-class rate. Browse coils on Amazon, order direct, or check Staples for pickup.
Best for international mail: Global Forever. One round design, one rate, every destination. Find Global Forever on Amazon or order from the source.
Best for collectors: Annual USPS Commemorative Collection. The yearbook-style set with every special release from that year, a favorite among philatelic hobbyists. Prices vary by year, historically in the $70 to $90 range. Check listings on Amazon, shop the yearbooks, or browse Walmart.com.
Best budget move: a single booklet from a grocery counter. Need one book today? Kroger or Publix at face value beats paying shipping on a one-item order. Walmart in store and CVS work the same way.
- Weigh the heaviest piece you plan to send on a kitchen scale.
- Match the denomination to that weight and destination instead of stacking extras.
- Pick the quantity that fits your habits: 20 for occasional mail, 100 for weekly batches.
- Buy from USPS or an authorized retailer, and walk away from any deep discount.
Need one book today? Find stamps at the grocery or pharmacy counter on your next errand. Mail every week? Order a coil online and keep a few Global Forever issues in the same drawer so nothing gets held up on the way overseas.
Common Questions About Stamps
How much does a Forever stamp cost right now?
The first-class rate changes whenever a new price is filed, which has happened once or twice a year recently, so any figure printed in a buying guide goes stale fast. Check usps.com for today’s number before ordering in bulk. The exact amount matters less than it looks: a book bought at the old price still carries a standard letter after the increase.
Do Forever stamps ever expire?
No. An issue bought years ago still mails a standard domestic envelope today no matter how many rate changes have happened since. The exception is older denominations printed with a dollar amount, which stay valid but count only toward that printed figure, so you combine them to reach the current rate.
What is the difference between Forever and Global Forever?
A domestic Forever pays for a standard letter inside the United States. Global Forever pays for international mail to any country on earth. They carry different artwork and different prices and are not interchangeable, so a domestic issue on an overseas envelope usually returns to sender.
Can I get a refund on postage I never used?
As a rule, no. USPS treats these sales as final and does not buy back unused stock for cash. Some retailers will exchange an unopened pane for store credit, but that is a store policy rather than a national rule, so ask before committing to a large quantity.
